I understand your not wanting to use those widgets, I don't have them on my forum either.

If you want a language translator on every page but don't want to use those widgets to achieve it, you could add a socialbar on your forum that will put a colored toolbar with the translaor on it at the bottom of your 'screen' on every page of your forum. You can design the bar with all the features you want it to have and the colors. You can add more things to the bar not just a language translator, like a facebook and twitter, a chatbox and more.

You would add the coding for it to your announcements. AP>>General>Announcements.
